Do you know any data storage technology for multi-user meter manufacturers ?
Multi-user electricity meter with high measurement accuracy, strong overload capacity, low power consumption, stable and reliable performance, small size, light weight, and convenient operation; easy to implement management, and adapted to the needs of different user groups such as industry, agriculture, civil use, etc.
Shandong multi-user power meter is a kind of power data collection instrument based on MCU and a large-scale power collection module. It has advanced functions such as multi-user power collection, remote data transmission, user power supply control, and multi-rate power metering. Small and powerful, it is welcomed by users in centralized power supply places such as college student dormitories and intelligent communities. For the flexibility of meter usage, there are some programmable parameters, such as meter number, number of metering households, communication rate, meter pulse constant, time value of multiple rate period, power supply status of each household, etc., as well as its metered data, That is, the power consumption of each user. Once these data are disturbed and damaged, not only the meter cannot work normally, but also economic losses to the user and economic disputes. Therefore, the data must be reliable, volatile, and non-volatile.
The power consumption of each user is converted into a pulse amount proportional to the power through a large-scale energy measurement integrated circuit (such as BL0933, ADE7755, etc.). After the photoelectric coupling circuit, the switch input interface is taken into the memory by the CPU According to the collected pulse amount, the CPU accumulates the power consumption of each user, stores it in a non-volatile memory, and the display circuit displays the power consumption of each household in turn. Remote transmission of measurement data through remote communication interface circuits (such as RS485, CAN bus).
Multi-user electricity meter manufacturers welcome you to consult for more related knowledge.
